1. 1. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Jimmy Atterstig; [2024]
   Keywords : Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

   Abstract : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. READ MORE

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Saga Arvidsson; [2022]
   Keywords : LBIC; Silicon solar cells; Busbar; Crystalline; LBIC; Kisel Solceller;

   Abstract : The importance of further research in the field of solar cells is crucial for the transition to cleaner energy. The aim of this project is to design and manufacture a contact system that can measure busbarless solar cells with an LBIC-system. READ MORE

4. 3. Exploration of bioactive additives for hyaluronan based hydrogels : A literature study

   University essay from

   Author : Tilda Eriksson; Lisa Quakkelaar; Alexander Parkstam; Alina Karlsson; Mansourah Askari; Shukri Said Ahmed; [2022]
   Keywords : Hyaluronan; Hyaluronic Acid; HA; 1; 4-Butanediol diglycidyl ether; BDDE; polynucleotides; mannitol; biomedical applications; dermatological fillers; fillers; Hyaluronan; Hyaluronsyra; HA; 1; 4-butandiol diglycidyleter; BDDE; polynukleotider; mannitol; biomedicinska applikationer; dermatologiska fyllmedel; fyllmedel;

   Abstract : Hyaluronan (HA) is a substance that is commonly used in biomedical applications in the form of hydrogels. One of these biomedical applications is dermatological fillers where HA is cross-linked with 1,4-Butanediol diglycidyl ether (BDDE) to reduce its rapid turnover within tissue. The filler gives a volumetric effect that can fill out wrinkles. READ MORE

5. 4. Use of a Sperm-Hyaluronan Binding Assay for evaluation of sperm quality in dromedary camels

   University essay from SLU/Dept. of Clinical Sciences

   Author : Anna Kotila-Ioannou; [2022]
   Keywords : Camel Semen; Dromedary camel; Sperm-Hyaluronan Binding Assay; sperm quality analysis;

   Abstract : The objective of this study was to assess the potential of Hyaluronan Binding Assay (HBA) to predict freezability and fertilization capacity of dromedary camel spermatozoa, and to determine if conventional sperm quality parameters and precursor of A-Kinase Anchoring Protein 4 (proAKAP4) values correlate with HBA results. Two semen samples were collected from each of six male camels. READ MORE

6. 5. Constructing an optical tweezers instrumentation and evaluation of trapping stiffness using the power spectrum method

   University essay from Umeå universitet/Institutionen för fysik

   Author : Haoxiang Yang; [2022]
   Keywords : ;

   Abstract : Optical tweezers can trap micron-sized objects such as cells, bacteria, and microspheres, and has become an important instrument for measuring forces associated with various physical and biological phenomena. In this thesis work, I constructed an optical tweezers instrument to trap 2µm diameter beads using a HeNe-laser operating with a wavelength of 632. READ MORE
